This standing bar has a daunting selection of 90 kinds of sake, including about 50 from local brewers, on its (Japanese-only) menu. Anticipating your needs, staff have made a cheat sheet in English of their top five local picks, all priced ¥880 by the glass. Look for the denim door curtains.
If you need food to power you through your tasting session, try the 'sake yoshiro course' (さけやしろコース; ¥3800), a set of six small seasonal dishes.
